Howard K. Stern, paramour and lawyer to fallen angel-temptress Anna Nicole Smith, is suing the holy heck out of Rita Cosby and her publisher, Hachette Book Group. Cosby's book, "Blonde Ambition: The Untold Story Behind Anna Nicole Smith's Death," which has pretty much only been read by tabloid mag staffers in need of innuendo for items, claims that Howard K. Stern and Anna Nicole babydaddy Larry Birkhead had an affair, for one thing. Birkhead's attorney—his client certainly has more case for grievance, because oh my God, Howard K. Stern, eww—says he'll file his own libel suit soon enough. Nifty! The legacy of Anna Nicole lives on!
